Kertas kerja ini membentangkan penilaian pelbagai teknik kepelbagaian koperasi yang digunakan untuk sistem penyiaran multimedia digital satelit (S-DMB) masa hadapan. Peningkatan kepentingan hibrid dan/atau rangkaian satelit dan daratan bersepadu dikaitkan dengan penggunaan teknik kepelbagaian ruang seperti kepelbagaian antena menggunakan pengekodan ruang-masa. Skim pengekodan ruang-masa boleh dijangka menghasilkan lebih banyak keuntungan kepelbagaian apabila bilangan antena pemancar meningkat. Walau bagaimanapun, kami tidak boleh mereka bentuk skim kadar-1 yang mencapai kepelbagaian penuh untuk lebih daripada dua antena pemancar. Untuk mengatasi had ini, skim kuasi-ortogonal telah dicadangkan, dengan mengorbankan kerumitan penyahkod dan keuntungan kepelbagaian. Dalam makalah ini, kami memperkenalkan skim pengekodan masa ruang kuasi-ortogon yang cekap, dan menilai pelbagai aspek yang berkaitan dengan aplikasi skim yang dicadangkan kepada sistem satelit. Skim yang dicadangkan dalam kertas ini menyediakan kadar penuh serta penyahkodan kemungkinan maksimum melalui pengesanan linear mudah.

Abstract: This paper presents an evaluation of various cooperative diversity techniques applied to future satellite digital multimedia broadcasting (S-DMB) systems. The increasing importance of hybrid and/or integrated satellite and terrestrial networks is associated with the utilization of spatial diversity techniques such as antenna diversity using space-time coding. The space-time coding schemes can be expected to result in more diversity gain as the number of transmit antennas are increased. However, we cannot design a rate-1 scheme that achieves full diversity for more than two transmit antennas. To overcome this limitation, quasi-orthogonal schemes were proposed, at the expense of the decoder complexity and diversity gain. In this paper, we introduce an efficient quasi-orthogonal space time coding scheme, and evaluate various aspects associated with the application of the proposed scheme to satellite systems. The proposed scheme in this paper provides the full rate as well as maximum-likelihood decoding via simple linear detection.
